Definitions
- the invention is formed by a method for clamping deformation-sensitive workpieces, in particular thin-walled rings, in which the workpiece to be clamped placed between the clamping jaws of a chuck in his chuck body below the jaws having a pole block with at least one magnet chuck, centered by the closing of the jaws and by the Magnet is fixed in this centered position.
- the invention further relates to a chuck for carrying out the method.
- the invention is therefore based on the object of specifying a method with which the disadvantages described above are avoided.
- the object of the invention is furthermore to provide a chuck with which the method according to the invention can be carried out.
- the process part of the object is achieved by the method mentioned, which exploits the fact that without further effort by the chuck, a centric clamping is achieved, so that before the machining of the workpiece in a simple manner its correct alignment is ensured. Furthermore, the use of the chuck also means that forces occurring during machining can not displace the workpiece, since this is fixed in a form-fitting manner by the clamping jaws of the chuck. It should be noted in the method according to the invention that the chuck, contrary to its customary usual determination is not necessarily used for clamping the deformation-sensitive workpiece, that such supportive use is, of course, but possible by a clamping force is generated in the centering serving closing the jaws.
- the magnet designed as an electromagnet is turned on, so that the centering of the workpiece can be done by the jaws without interfering interaction with a permanent magnet.
- the field strength of the electromagnet is increased in dependence on the speed for at least partial compensation of the centrifugally induced clamping force loss of the clamping jaws, so as to reliably secure the position of the workpiece.
- the clamping force itself is increased depending on the speed for at least partial compensation of the centrifugally induced clamping force loss of the clamping jaws.
- the field strength of the electromagnet is increased after removal of the clamping jaws.
- a chuck which can be designed manually or power-operated and which is characterized in that this several radially on a Having chuck guided clamping jaws, and that in the chuck body below the clamping jaws, a pole block is arranged with at least one electromagnet.
- the integration of the pole block with an electromagnet within a well-known in its basic structure of the prior art chuck offers the possibility that just this, the basic structure of this chuck can be maintained and in particular the adjustability of the clamping jaws is not affected by the pole block arranged below.
- Electromagnet or electro-coil assemblies of a plurality of electromagnets are arranged, such that adjacent magnetic regions have a different magnetic polarity. By this arrangement, a large field strength can be achieved with a low design effort. Furthermore, it is advantageous if 6 jaws and 6
- Magnet regions are provided, as this results in a reasonable compromise between equipment expense and circumferentially uniform force on the deformation sensitive workpieces.
- each magnet region (5) has areas of different polarity by centering, since it is thus also possible to use any, even odd number of clamping jaws.
- Fig. 1 is a front view of a chuck according to the invention in a schematic representation with a clamped bearing ring.
- FIG. 1 shows a chuck body 3 in which a plurality of, namely 6 clamping jaws 2 are radially guided, in which
- each magnet area 5 can also have areas of different polarity by centering, adjacent areas containing adjacent magnet areas remaining unchanged in their different polarity. Magnetic regions 5 are defined by these electromagnets 4, with adjacent magnetic regions 5 having a different magnetic polarity.
